Abstract/OtherAbstract:
Campylobacteriosis is the most reported bacterial-mediated gastroenteritic disease in many developed countries. Broiler chickens are a natural host for Campylobacter spp., and contaminated poultry meat products are a major source for transmitting pathogenic Campylobacter strains to humans. Currently, no intervention measure efficiently and effectively controls this pathogen in poultry flocks. Medium-chain fatty acids (caproic, caprylic, capric, and lauric acids) show a marked anti-Campylobacter activity in vitro. However, in recent trials using our in vivo models, administering these acids to the feed of broiler chicks neither prevented nor reduced cecal C. jejuni colonization in broilers. In the present study, we examined whether a drinking water application of medium-chain fatty acids might be more effective in combating Campylobacter colonization in poultry. Although Campylobacter colonization and transmission was not reduced, we demonstrate that adding an emulsion of a mixture of caproic, caprylic, capric, and lauric acids to the drinking water of broiler chicks reduces their colonization susceptibility and prevents C. jejuni survival in drinking water. Thus, the merit of water applications of medium-chain fatty acids is the reduction of the probability of Campylobacter entry into and transmission throughout a flock.
